IGBT replacement
Hi guys, I'm repairing a welding machine which has 12 blown IGBTs in the power supply. The blown IGBTs are no longer available and has a replacement part that has lower power dissipation. The original IGBT is SGP30N60HS (250w) and the replacement is IGP30N60H3 (187w). Is there a problem to change with the replacement part or I have to search with higher power dissapation -

Re: Help about finding crimp connector
I have extracted another crimped wires from another PSU but they look different. They are used to hold the strands together on multiple wires so they don't move during soldering.I'm looking for such crimp terminals, but I can't find any. Please help me find some....Leave a comment:
